Umbilical cord anomalies are rare. The differential diagnosis for a cystic structure around the umbilical cord and its insertion include pseudocyst, omphalomesenteric duct cyst, haemangioma, omphalocele or anterior abdominal wall defects. Although cord anomalies can be detected through antenatal ultrasound scans (US), very often a definitive diagnosis cannot be made. This may affect the management of the infant at birth. In cases where antenatal US was not diagnostic, current evidence supports the use of MRI to help in making an accurate diagnosis. We report two cases of umbilical cord anomalies. The first case was diagnosed in antenatal US as an omphalocele, but was found to be an allantoic cyst with hamartoma on postnatal diagnosis. The second case was not detected on antenatal US, and was diagnosed postnatally as a small omphalocele with vitellointestinal duct remnants.
脐带异常较为罕见。脐带及其附着处周围囊性结构的鉴别诊断包括假性囊肿、卵黄管囊肿、血管瘤、脐膨出或前腹壁缺损。尽管可通过产前超声扫描（US）检测到脐带异常，但通常无法做出明确诊断。这可能会影响婴儿出生时的处理。在产前超声检查未能确诊的情况下，目前的证据支持使用磁共振成像（MRI）来辅助做出准确诊断。我们报告两例脐带异常病例。第一例在产前超声检查中被诊断为脐膨出，但产后诊断发现是伴有错构瘤的尿囊囊肿。第二例在产前超声检查中未被检测到，产后被诊断为伴有卵黄肠管残余物的小型脐膨出。
